18. What is the provision regarding leading questions?
Leading questions are prohibited during examination in chief and re-examination.
There is no bar on asking a leading question during cross examination. This means
that one cannot ask a leading question from one’s own witness; but can ask a
leading question from the witness presented by the opposite side.
This general rule has an exception viz. that there is no bar on asking a leading
question which is introductory in nature. E.g. You are in the working in the store
since 2010?
